Question

I am having this error and have installed RDLC report to my Visual Studio and have a controller that exports RDLC report to Excel. Now when I try to run view.cshtml and get this error

"the tag RDLReportViewer does not exist in XML namespace 'clr-namespace:DSoft.RDL;assembly=RDLCPrinter. Line 11 Position 10".

//Window.xaml

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:RDLC="clr-namespace:DSoft.RDLC;assembly=RDLCPrinter"
        x:Class="RDLCDemo.MainWindow" 
        Loaded="Window_Loaded"
        Title="RDLC WPF UserControl Demo" Height="800" Width="1024">
